It’s taken me 35 years to get to Portugal but I’m finally here for a vacation. Our first stop was this shop in Porto called Saber-Fazer.
They have wool weaving yarn on cones. The colors are limited but they have a fine wool yarn that is close to the Harrisville Shetland. There might be a worsted weight too.
I bought a cone along with some skeins of yarn and I look forward to experimenting with it.
It’s all Portuguese sheep/yarn. They also have fleece and other miscellaneous weaving/carding/dyeing.
Their website is quite good though I question the mailer bag they ship in. Mine disintegrated while walking back in the rain.
Not sure how expensive shipping would be to Switzerland and if they would exclude the VAT for you.
There’s also the famous retrosario Rosa Pomar shop in Lisbon. It’s mostly knitting yarn. Maybe we can bombard them for coned yarn in the various sheep varieties she’s been promoting… someone is milling and spinning it. She wasn’t in the shop so I couldn’t ask.
I hope you had some luck!
